County Codes for Alabama License Plates

Back in 1941, Alabama created a numerical county-code system to help with assigning license plate numbers to vehicles. When the system originated it was decided that codes 1, 2, and 3 would go to the three most populated counties, which at the time were Jefferson, Mobile, and Montgomery. After these three, then the rest of the Alabama counties were listed out in alphabetical order and assigned codes 4 through 67. Later, the codes 70 and 80 were added for replacement plates and supplemental plates.

Over the years the populations have changed throughout the Alabama counties, with Madison making its way to be the third most populated county in the state. Madison’s plates, however, will still be marked with a 47 instead of a 3, as in order to make the change the law itself would need to be altered.
